Please help

Imagine a circuit as shown below, with parallel plate capacitors with empty space
(vacuum) between their plates, and with the value for C equal to 0.155 F.
a. What is the equivalent capacitance for the entire circuit, in terms of C? What is this
value numerically?
b. Given a battery with potential difference, AV = 12 V connected to the circuit, how
much charge will accumulate on each of the three capacitors?
c. How much energy will each capacitor store, in Joules? d. How much energy will the
entire circuit store?
e. Explain how your answers to parts b, c and d would change if these capacitors were
filled with some dielectric material.
